Abstract
The present invention provides touch sensors that incorporate electrodes that are capacitively coupled through a dielectric layer to one or more resistive touch sensing layers, for example for linearizing the electric field across the resistive layer of an analog capacitive touch screen or for addressing the conductive elements of a matrix type capacitive touch screen. Such a construction allows for new manufacturing methods and new ways of constructing touch sensors.
